Drive frame and assembly for mining apparatus

Abstract

A drive frame for the drive assembly of a mining installation has a pair of side plates and a connector. The mining installation is of the type having a winning machine and a conveyor. The connector is fastened to one of the side plates of the drive frame and constitutes means for mounting respective drive units for the winning machine and the conveyor. The connector is constituted by a respective mounting plate for each of the drive units. The two mounting plates are connected to one another in a tension-proof manner. The connector is provided with an annular collar which mates with an aperture in said one side plate to support and align the connector.

I claim: 
     
       1. A drive frame for the drive assembly of a mining installation constituted by a winning machine and a conveyor, comprising; a pair of side plates for said drive frame, a connector fastened to one of the side plates, the connector including means for the connection of respective drive units for the conveyor and the winning machine, the connector having a respective mounting plate for each of the drive units and each of the mounting plates being connected to one another in a tension-proof manner, an annular collar extending into an aperture in said one side plate to support and align the connector, and coupling means for locking the connector to said one side plate in a non-rotational manner, the coupling means being spaced from the annular collar. 
     
     
       2. A drive frame according to claim 1, wherein the two mounting plates are formed integrally with one another so that the connector is of one-piece construction. 
     
     
       3. A drive frame according to claim 2, wherein the connector is a one-piece casting. 
     
     
       4. A drive frame according to claim 1, wherein the coupling means comprises a key on the connector and a matching groove in said one side plate. 
     
     
       5. A drive frame according to claim 1, wherein at least one of the mounting plates is provided with an oil-retaining cavity. 
     
     
       6. A drive assembly for a mining installation constituted by a chain-driven winning machine and a chain-driven conveyor, the drive assembly comprising a drive frame and respective drive units for the winning machine and the conveyor, the drive frame having a pair of side plates and a connector which is fastened to one of the side plates, the connector having two mounting plates connected to one another in a tension-proof manner, the two drive units being mounted side-by-side on the mounting plates of the connector, and an annular collar extending into an aperture in said one side plate to support and align the connector. 
     
     
       7. A drive assembly according to claim 6, further including a chain drum for driving the conveyor, said drum mounted within the drive frame and aligned with the aperture in said one side plate. 
     
     
       8. A drive assembly according to claim 6, wherein the mounting plate of the drive unit for the winning machine is constructed as a chain sprocket case. 
     
     
       9. A drive assembly according to claim 6, wherein the conveyor drive unit mounting plate is provided with an oil-retaining cavity. 
     
     
       10. A drive assembly according to claim 9, wherein said cavity is annular and surrounds the bearing of the output shaft of the conveyor drive unit. 
     
     
       11. A drive assembly according to claim 6, wherein the connector is provided with connection means for a hydraulic advance ram. 
     
     
       12. A drive assembly according to claim 11, wherein said connection means is formed on a projection welded onto the connector. 
     
     
       13. A drive assembly according to claim 6, wherein the connector is connected to said one side plate in such a manner that all the tensile forces of the winning machine chain are transmitted into the drive frame via the annular collar. 
     
     
       14. A drive frame for the drive assembly of a mining installation constituted by a winning machine and a conveyor, comprising a pair of side plates for said drive frame, a connector fastened to one of the side plates, the connector having means for the connection of respective drive units for the conveyor and the winning machine, the length of the connector exceeding the length of said one side plate, the connector including a respective mounting plate for each of the drive units and each of the mounting plates being connected to one another in a tension-proof manner, and an annular collar extending into an aperture in said one side plate to support and align the connector.
